Factors affecting semen quality and their effects on the fertilizing ability of broiler breeder spermatozoa using a fluorometric assay

Creator:: Bootwalla, Salim Mohsin
Abstract:: Three distinct studies using an ethidium bromidedigitonin fluorometric assay were conducted to determine if the fertilizing ability of individually caged broiler breeder males (BBM) could be enchanced by nutrition, breeding and semen extender viscosity. The first study evaluated the effects on the spermatozoal quality of BBM by feeding corn-soybean meal...

Estimates of genetic variability resulting from single, top, and double cross populations in durum wheat (Triticum turgidum L. var. durum)

Creator:: Abdennadher, Mourad
Abstract:: The success of a plant breeding program depends upon the availability of useable genetic diversity. Such diversity may be enhanced depending on the type of hybridization strategy employed. Segregating progenies resulting from F2 populations, a double cross, and a top cross were compared for the amount of useable genetic diversity...

Effect of ethanol and low dietary copper on perinatal and postweanling copper utilization in the rat

Creator:: Baek, Jong Ho
Abstract:: The hypotheses of this research were (1) to test if the antagonistic effect of ethanol on liver copper could be seen within a short period when ethanol ingestion, low dietary copper and high metabolic demand represented by either pregnancy plus lactation or rapid growth are simultaneously present and (2) to...

Characteristics of Northern squawfish (Ptychocheilus oregonensis) and feasibility for utilization as human food

Creator:: Lin, Dongdong
Abstract:: The characteristics of Northern squawfish (Ptychocheilus oregonensis) and the feasibility of utilization of this species for human consumption were investigated. In the first experimental phase, the iced storage characteristics of squawfish were determined. Quality changes were monitored over 24 days of storage by chemical, physical, microbiological and sensorial methods of...

A model for understanding the influence of selective and nonselective harvest on fish populations

Creator:: Hirai, Takayuki
Abstract:: To understand the influence of selective harvesting on the adaptive capacity of fish populations in changing environments, a computer simulation model was developed. In the model, hypothetical populations were composed of five different life histories, which were genetically determined. Each life history type had its own rate of survival and...

The thermal characteristics of hydrologically intact Type C and E streams in eastern Oregon

Creator:: Hopkins, Karl T.
Abstract:: Many streams in eastern Oregon are listed as water quality impaired on the basis of water temperature. However, it is often difficult to predict water temperature for these streams even if there are no anthropogenic impacts. We measured air and water temperature and stream characteristics on three Type C and...

Evaluation of combining ability in mosquitofish

Creator:: Pongthana, Nuanmanee
Abstract:: Two replications of a half dial lei cross experiment were performed among four inbred lines of mosquitofish, Gambusia affinis. These inbred lines originated from three random-bred stocks: OR, TX and CD. The experiment was conducted as a completely randomized design. Experimental material consisted of parental lines and F₁ populations maintained...
